Citrulline antibody is an immune protein (antibody) that binds to a nonstandard amino acid (citrulline) that is formed by removing amino groups from the natural amino acid, arginine. A chemical process known as citrullination causes this change to occur. Citrulline antibodies are measured with a blood (serum) test that is analyzed in laboratories. The test is also known as anti-citrulline antibody, cyclic citrullinated peptide antibody (CCPA), anti-cyclic citrullinated peptide antibody, and anti-CCP. Research suggests that in the joints of patients with rheumatoid arthritis, proteins may be changed to citrulline as part of the process that leads to inflammation of the rheumatoid joint.
